Abstract
A solar cell charging device includes a base shown as a shell shape, a light-converging lens arranged at a top face of the base, a solar collector correspondingly located under the light-converging lens and a photoelectric converting unit. A plurality of charging troughs arranged on the base are recessed inwardly from circumferential faces thereof. The photoelectric converting unit is connected between each charging trough and the solar collector, converting the light energy absorbed by the solar collector into electric energy provided to be input into each charging trough, after the light-converging lens focuses the solar energy onto the solar collector.
